- 6CO2 + 6H2O → C6H12O6 + 6O2: Photosynthesis
- C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP: Cellular respiration
- C6H12O6 → Lactic Acid + ATP: Anaerobic respiration
15. C. The number of atoms in the reaction don't change
1. The correct answer is D. Breaking down glucose in cellular respiration is the main way organisms get ATP.
2. The incorrect option is A. Polymers. Polymers are a category or type of biomolecule, not one specific biomolecule.
3. The correct matches are:
- Lipids: Fatty acids
- Nucleic Acids: Nucleotides
- Carbohydrates: Monosaccharides
- Proteins: Amino acids
4. The correct answer is B. ATP is energy produced through cellular respiration.
5. The correct answers are:
A. True. Lipids are a major component of cell membranes.
B. False. Carbohydrates are good for short term energy, while lipids are good for long term energy.
C. True. All biomolecules contain carbon, hydrogen, and oxygen.
D. False. A covalent bond is when electrons are shared between elements, not transferred.
6. Plants obtain glucose through photosynthesis, while animals obtain glucose through eating.
7. The correct answer is A. Genetic information is stored in nucleic acids.
8. The required biomolecules for us to live are:
- A. Carbohydrates
- B. Lipids
- C. Nucleic Acids
- D. Proteins
9. The correct answer is D. Yeast eats carbohydrates like sugars to create CO2 and make foods rise.
10. Food serves as the reactants for the chemical reactions, and the biomolecules our body uses are the products.
11. The main purpose of enzymes is to lower the activation energy to make processes proceed more quickly.
12. The correct answer is C. Photosynthesis is an endothermic reaction, meaning it absorbs energy.
13. The reliable sources are A. 2021 Science textbook and D. Peer-reviewed journal.
14. The equations match the following:
